Application september 17, 1945, serial No. 616,785

' 35 claims. (c1. 21e-29) My invention relates particularlyfto devicesfor dispensing and/or applying adhesive tapes, and more especially to amanipulatable device for applying pressure-sensitive adhesive tape toobjects as for packaging, reenforcing, sealing, af-

xing or other purposes. It'Will be understood, however, that manyfeatures of my invention are applicable generally to devices for usingor Workfing adhesive tape.

It is an object of myinvention to-provide 2.110

simple device that can be' gripped and 'operated by the hand to dispenseand apply pressure-sensitive tape to objects without requiringthatcontact be made with the tape by the hands.`

It is another object to providesuch a device which is adapted forapplying any -`o`f a variety of tapes including heavy tapes,-relativelywide tapes or laminated pressure-sensitive tapes, particularly thosehaving the adhesive sidecovered Valong the central portion thereof andknown in adapted to prevents the` user, when replacing a. supply roll oftape, from installing the new roll 'in an incorrect position, and it isa further object 'in this respect to provide novel and improved mountingarrangements for the tape roll which are adapted to permit the roll tobe inserted in only a correct relation to the tape-feeding means.

It is another object to control automatically the feeding of a startinglength-of tape and the 'severing of the applied tape from the tapesupply roll by movementV ofthe device across vthe object L.to which thetape'is applied. Y Y It is another Volojectto provide such'a device p40Vhaving novel 4and improved meansl for printing characters-for example,any desired trade name `--on the adhesive side ofthe tape as the tape isdrawn from the supply roll. v

It is another object to provide a hand device s45 which is. adapted forvapplying tape'around cor- `lners and edges of packages, cartons, .orthe like.

My tape applying device comprises a housing 'for a supply'roll ofadhesive tape in Awhich there l is provideda mechanism for feeding out ashort50 length of tape, to serve as a starting length for application toan object upon setting the device thereon, and furthenincluding meansfor sever- *ing thetape from the supply. roll. 4By way of 4lexample, onemay use the device by. settingitea'u rst on the object to which the tapeis to be applied, then operating the feed mechanism to feed out astarting length of tape, next moving the vdevice across the object todraw the tape from the supply roll and apply it progressively to theobject, and thereafter severing the tape when a desired length has beenapplied.

`A feature of my invention is to provide such a 4device whereinoperation of a control in one direction causes the starting length tobefed out, and release of that control causes the tape which has beenapplied to the object to be severed from the supply roll.

. Other objects and features of my invention lie in the details ofconstruction, combinations of elements and arrangements of parts of theillus- -trative embodiment herein shown and will be apparent from thefollowing description and appended claims.

The preferred embodiment offmy invention shown in the accompanying.figures comprises a.;

housing I, formed for example of :metalby die vcasting or of plastic bymoulding, having afhandle 2 at the top andthe bottomv thereof open.l Thehousing has an openable sidewall or.. door 4,

which is hinged .for exampleto the. main heus-:f

ing as shown in Figure 2,-.t0permitaccess to the internal mechanism andreplacement of thetape supply. The tape supply is l in-the, formof aroll 6 of pressure-sensitive tape,.which is supported in the rearwardportion ofthe housing..

In the forward portion of the housingthere is a tape feedingandsevering. .mechanism 'IL herein referred to sometimes as thedispensing mechanism, and between ther roll and. .dispensing mechanism,there is a tapeprinting mechanism:

adjacent the left side thereofy (opjrosite` the door.

4) and a right verticalsi'de wall 9c at the front of the housing only."(See' Figures 1-3-8 and 10.) The left side 9b is secured by screwsI0`to bosses la on the inner left wall ofthe housing (see Figures 3, 8and 9) and is bracketed to the-rear .a

wall of the housing lat V-3 as shown in Figure 1.

One preferred mounting 'arrangement for the tape rolls comprises` ashaftiIfI'Ksee Figures 5 and 13) having amounting flange IIa at its baseend held by screws I2 to the vertical frame wall-r 9b. This shaft hasatape-roll locating'means at its base portion comprising'preferably ashaft portion IIb of enlarged diameter. T'he roll has a core I3 providedwith an axial opening .13a

`it require anylarger carton for packaging the :tion of the shaftextendsbeyond the core.

extending portion has preferably a groove I I c adapted for receiving aspring clip I4 for retainvafter referred to as the stripping member.

4 instance enlarged in diameter so as to conform to the shaft and permitthe roll to be mounted thereon in only one axially directed pisitionrelative thereto. The opening I3a is so axially directed with respect tothe direction of the winding of the tape on the roll that as the tape isdrawn from the roll towards the feed mechanism, whiley the roll is in acorrect mounted rposition,vthe`adhesive si'd'e of' the-tape faces in thedesired direction. In the present embodi- J ment, the free tape 6a ispulled forwardly from kthe roll as shown in Figure 1, and the roll ismuntedsothat the adhesive side of the tape En. 'facesupwardly.v Theshaft II has a length f-such that when the roll is correctly placedthereon in a fully mounted position a free end por- This ing the roll onthe shaft. This clip is preferably provided asa permanent part of thecore t3l as shown, so that the roll can be attached in .one manipulationof the hand without having to ,detach temporarily any parts that mightbecome lost; also this retaining means always assures .tional one (withrespect tothe direction of the Winding of the tape` on-the roll) whichenforces .the user, when replacing the tape roll 6, to installthenewrollin correct relation to the tapefeeding mechanism; This is veryimportant in .machines using adhesive tape, especiallypressure-sensitive tape, v because la Asuccessful operation of thelmachine requires that the advesive side of the tape as it is drawn fromthe roll, be proporlydirected with respect to the machine.

.Certain advantages, of the mounting above described are that it uses.avery simple core hav- .ing no elements extending beyond the sides ofthe roll. Although such-a core is provided as a permanentpartloffeachroll, it does not increase appreeiablyv the cost ofthe rollnor does roll.. Y f At the front of theapplyingV device there is a Astartingl length 6bof-thetape is fed out l tlirough-a bottom-opening'.I5 of the frame 9, as

illustrated in Figure I0. by a tape feeding mechanism which'forms acomponent of the dispensing mechanismi aforementioned. The feedingmechanism comprises a. wheel I6 having a series of sharply pointedpins-l1 projecting from its periphery which engage. lthe tape from thenonadhesiveside-and, drivingly yhold the tape to the wheel. (Thispinwheelis described. in my Patent No. 2,441,821, dated May `18,;1948.)The pinwheel -lies between therarms; Ila'of- 'aLU -shaped lever I8 (see'Figures l and-ill and-is= journalled. on a. shaft I19 which issupportedat its ends by intermediate .portions of` the'arms. Id.; vApartI8b of lever t8 bridges the arms-If8a at the front of the pinwheel andis' substantially tangential to the zwheel.

This'part. serves to, strip the tape from the pins 'I'I as-the wheel isturned, and is here- In this. member there is a slitv 20. for clearingit of which is recessed at one end--i e., in the presente-,u the pinsIl..- Therearward-portions of the arms tala are offsetl at 2| awayfrom'one another so as to lie adjacent the frame sides 9b and 9c, andare pivoted to these sides by pins 22 supported at' their inner ends bylugs 23 turned over from the framed sides. Connected to the shaft |19 isa control arm 25 which extends upwardly through a guide 26, turned overfrom the frame side 9b. and onwardly through an opening 21 in thehousing i. On the end of this arm there is a thumbpiece 25a which is atthe left side of the handle 2 where it can be conveniently depressed bythe thumb while the handle 2 is gripped with the right hand. Thethumbpiece is normally held raised by a tension spring 28 connectedbetween the arm 25 and guide 26. As the thumbpiece is depressed, thepinwheel I6' is rocked bodily downwardly about the pivot pins 22 ascenters, and when the thumbpiece is released, the pinwheel is returnedby the tension spring 28 to its initial position. The limiting positionsof the pinwheel are defined, for example, by the abutment of the shafti9 against the ends of slots 29 provided in the frame sides 9b and 9c.

As the pinwheel is moved bodily downwardly it is caused to rotate in acounterclockwise direction, as viewed in Figure 8, so that it willpropel forwardly a starting length of tape. This rotation is produced byengagement of a pawl 30, which is pivoted at 38a to the right frame'side3c, with a ratchet wheel 3| mounted on the right side of the pinwheel,as shown in Figures 3 and 8. rhe length of tape which is so propelledforwardly is' stripped from the pinwheel by the stripping member |812and directed downwardly towards the opening as isherein next explained.

At the lower end of the stripping member |8b there is a tape-holdingmember 32`having a hat narrow surface for contacting the adhesive sideof the tape. This holding member is provided with side arms 32a whichare secured to a shaft 'lxthat is pivoted to the arms of the lever I8.Under influence of a tension spring 34 the holding member is biasedclockwise, as Viewed in Figure 8, against the Vadhesive side ofthe tapeto clamp the tape against a lower bevelled face |8c of the strippingmember |812, the place where the tape is so clamped being at a distance,say 1/2 inch, from the free end of the tape. During approximately therst two-thirds of the down- I `ward stroke of the control arm 25, thepinwheel i6 feeds forwardly a short slack length of tape .above theholding member 32,.while the latter continues to clamp the tape againstthe stripping member 18h. During the last one-third portion of theforward stroke, the pinwheel continues to feed forwardly the tape;however, the holding member is now cammed counterclockwise lby a meanshereinafter described, reaching -nally the position it occupies inFigure 10. As the holding member leaves thegstripping member, it holdsto the tape by adhesive contact and A- serves to direct the startinglength of tape (which lis in advance thereof) through the opening |5.

AAlso by its counterclockwise movement, it directs This roller is movedbod-* *through the opening |5 below the housing las* shown in. Figure10). The tape-contacting surface of-:the holding member 32 issubstantially tangentialto the roller 35 so that it will hold eachstartingflen'gth of tape adjacent to the roller. In thexcounterclockwisemovement of the holding member, abovementioned, the starting length oftape is moved underneath the roller. An important featiireof the presentdevice is that this movementof the tape occurs before the roller reachesits downmost position. Thus, the thumbpiece 25d, may be depressed beforeor after the devjice is seated onto an object and in either case alength of tape of approximately 1A inch will be applied to the' object.

- Uponpushing the device forwardly across the object after applying thestarting length of tape thereto, the tape is iirst pulled free from theholdingmember because the tape has substantially less larea of contactwith the holding member than it has with the object. that the-tapedisengage more easily from the holding' member the tape contactingsurface of the holding member is positioned so that as the tape'is'drawn around the roller 35 the adhesive i side thereof is more thandegrees, instead of substantially 180 `degrees as shown, from theadhesive -side of the tape contacting the holding member.) Thereupon,with continued forward movement of thedevice the tape is caused to bedrawn from the supply roll 8 around the pinwheel I and to be pulled outthrough the opening i5 and applied progressively to the object. When thedesired length has been applied, the tape issevered adjacent to itspoint of exit from the housingby releasing the thumbpiece 25a as isherein next described.v

The tape-severing means comprises a blade 35 shown in detail in Figure15. This blade has two arms 35a pivoted on the outer ends of the shaft33, the blade thus straddling the holding member 32 and being pivoted ona common axis with the `holding `member and pressure roller 35. Theblade'has a sharp razorlike edge 36h which may be inclined to its pivotaxis; for some purposes it mayalso be desirable to have this edgeserrated. The blade is urged clockwise under influence of a tensionspring 31 connected between the right arm thereof and right frame wall9c, and is controlled by coaction of a pin 38, which is in the leftarmvthereof, with a cam 39 provided in the left frame side 9b. This pinand cam also control 'the holding member 32, the p-in being for thispur- '-po`se extended rightwardly into eng-agement with `a`n arcuateslot 32h provided in the left arm 32a of this member.

When the feed mechanism is in initial position, the left'end of the pin38 engages the uppermost "part of the cam 33 and holds the blade 36 in aposition underneath the roller 35 as shown in Figure 8.V At this timethe pin is in the rearward part of the slot 32D, and the holding memberis clamped This cam 39,"then` bent rearwardly and next inwardly "atthecenter of the cam, the spring being held against the front face ofthis inner part of the lug by screws 42.

distance back from the severing means. By this clamping operation thefree end portion of .the tape is held xed in relation to the wheel I 6throughout the remainder of thereturn stroke.'

Since the pivot 22, about which the pinwheelis rocked, is located near astationary place past which the tape is drawn from the roll 6, itwill beunderstood that during the portion of the return stroke following thesevering ofy the tape, there is no pull exerted on the tape-to draw itfrom the roll nor is the tape between .the pinwheel and the rollpermitted to develop any appreciable slack. The pinwheel thus returnswithout any appreciable resistance on it. Also,` by keeping the tapesubstantially taut against the pinwheel, there is no chance forfthe tapeto become disengaged from thel pinwheel or the printing mechanism. .i

While I have described theY applying .device as a hand operable one, itwill be understood that my invention contemplates that such device may,alternatively, be power driven for automatic packaging. l 1

The tape printing mechanism above referred to is located between thetape roll 6 and pinwheel I6 above the level of the tape 6a drawn fromtheroller as shown in Figure 1. This. printing mech- .anism comprises aflexible printing band 45 which contacts the adhesive side of the tape6a. This band is carried on a pair of vertically spaced rollers 46 thatare journalled on shafts 41 supported by the frame side 9b. The rollerspreferably are flanged'for retaining the band thereon. The band is heldunder slight tension so that it can be readily removed and replaced byanother as desired. On the outer surface of this band are raisedcharacters for printing designs, written material, or the like, on thetape. Frictionally engaging the top portion of the printing band 45 is aband 48 having a roughened exterior surface. This band is supported inan'upwardly inclined position on two rolls 48 which are journalled onshafts 58 and supported also from the frame side 9b. On the outer endsof the shafts 41 and 50 there are respective'side plates 5| Aand 51a forholding the shafts firmly in their spaced relationship.

Slidably contacting the top surface of the band 4.8 is a printingmaterial as of colored chalk in The cake rests on the band 48 but isheld from falling out lof position, should the device be tilted orinverted,

by being pivoted at its lower rearward portion on a rod 53; this rodbeing supported by the left frame side 9b just above the rearward partof the band 4B. Also, atthe rear of the cake there is a stop 5t limitingits` angular travel away from the band 48. Preferably, some slighttension of the cake of printing material against the band, in additionto that provided by its weight, is desired. This is done by a lightspring 55 anchored suitably to the frame side 9b.

, .As the tape 6a, is drawn fromrthe roll 6, it is pulled against thelower portion of the printing band 45 and turns the band by its adhesivec ontact therewith. rAt the same time the band' 45 vfrictions-illydrives the suply band 48 and causes lthe surface to slide across thebottom face of the cake 52. By this sliding contact the band 48 rubs oilprogressively a powder from thelcake and car- 1 ries the powder totherband 45, depositing the powder on the raised characters ofthe'printing band. When these characters next engage the tape theadhesive on the tape picks up the'` powder and characters are. printedon the tape.` This printing'.A
